| (54) | Optical indicia reading terminal with color image sensor |
| (57) An optical indicia reading terminal can comprise a microprocessor, a memory, and
an image sensor integrated circuit, all coupled to a system bus, and a hand held housing
encapsulating the two-dimensional image sensor. The image sensor integrated circuit
can comprise a two-dimensional image sensor including a plurality of pixels. The image
sensor integrated circuit can be configured to read out a plurality of analog signals.
Each analog signal of the plurality of analog signals can be representative of light
incident on at least one pixel of the plurality of pixels. The image sensor integrated
circuit can be further configured to derive a plurality of luminance signals from
the plurality of analog signals, each luminance signal being representative of the
luminance of light incident on at least one pixel of the plurality of pixels. The
image sensor integrated circuit can be further configured to store a frame of image
data in the terminal's memory by converting the plurality of luminance signals to
a plurality of digital values, each digital value being representative of the luminance
of light incident on at least one pixel of the plurality of pixels. The optical indicia
reading terminal can be configured to process the frame of image data for decoding
decodable indicia.
